Mdmp 1206 005 Dual Quads On A Small Block Twin Win Or Double Trouble Part 1

3 We found the Holley 670 (PN 83670) to work great right out of the box, particularly on the Cobra intake. It's clearly an easy route to making good power, and the aluminum construction is an appreciated weight savings. Compared to the pair of traditional Holleys we'll be running as a pair in later tests, this single aluminum carb saves roughly 15 pounds.
